When to Choose SQLite Over MySQL? Pros, Cons, and Ideal Use Cases

Preface

When packaging a project that includes MySQL into a container, the MySQL image feels huge and takes a long time to pull, especially on a server with limited resources.

Considering SQLite as an alternative because of its small memory footprint raises the question of what compromises it makes; this article explores those trade‑offs.

First Impressions of SQLite

It behaves like a .txt file, embedded directly in the application rather than running as a separate service.

Cross‑platform support on Windows, macOS, and Linux.

Lightweight : the entire library is only a few hundred kilobytes.

Backup is as simple as copying the database file.

When to Use SQLite?

SQLite is ideal for rapid prototyping, Minimum Viable Products (MVP), or situations where server resources are scarce. You can quickly store data with SQLite and an Express server, test APIs using a .http file and the REST Client plugin, and later replace SQLite with a more robust database such as MySQL or PostgreSQL.

What Is the Cost of Being Lightweight?

Everything has a price. The drawbacks of SQLite include:

It does not handle high‑concurrency writes well, making it unsuitable for many production workloads.

Frequent file I/O can cause stutter because there is no separate server layer to buffer operations.

It is limited to local access; you cannot connect to it over the network like MySQL.

Conclusion

Use SQLite for prototype development or when you have very limited server resources and no high‑concurrency requirements. If the application needs to support high concurrency, skip SQLite.
